mylemonblue, thank you for the links, messiah website was a very interesting read ghonma, thank you for the link to zBrush, it all helps Helgard, my inquiries were not meant to demean or insult 3d artists and their work, much of which is amazing. I am sorry I am being vague, but I am working on the tools for the artist, not the art. I sincerely hope my imprecision did not offended you in any manner, but if I did, I offer a sincere apology. Anton, interesting info. You probably are aware of this site, but it popped up in an search I ran earlier. http://www.uni-regensburg.de/Fakultaeten/phil_Fak_II/Psychologie/Psy_II/beautycheck/english/index.htm Thanks for your help. ccotwist3D, thanks for your help. Funny thing is I went to Silo and was baffled with deja vue. I have been going though so much info that the name Silo did not immediately ring a bell, I was staring at the site and was positive it was actually the identical information to an entirely different application. It was an amusing 15 minutes trying to resolve my confusion. I truly appreciate all of the assistance, I figure I have at least another month of research ahead of me. Next step will involve confirmation the applicability of the processes to be employed. This is a very major undertaking based on a clean sheet concept. It is such a major project, I let it sit for all these years because I was sure some major software house would have tackled it by now. To date I have located nothing but some very tangential work. I am going to keep searching to confirm this. After all these years, I figure I should at least attempt to develop these concepts. Best regard to all, Steven (Torino)
